[0002] In inkjet printing, the size of the ink droplets ejected from the nozzle is generally 5 / 7 / 12PL. Due to the different sizes of the ink droplets, when the ink droplets fall vertically, the air around the ink droplets will flow upward, and when the paper moves It will also drive the flow of air to form the gap airflow between the nozzle plate and the printing paper. The upward air flow and the airflow of the paper moving form a turbulent flow, such as Figure 2-4 As shown, the reason for the formation of turbulence, under the action of turbulence, the ink droplets will converge regularly. When these ink droplets fall on the paper, it will cause black and gray on the paper, resulting in the printing of pictures or shading The quality has deteriorated, so it needs to be improved

Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0018] refer to Figure 1-6 , an inkjet method for improving printing quality, comprising the steps of:
[0019] S1: First modify the ink drop data in the ink drop data storage, and the ink drop data program modification code is as follows: figure 1 shown;
[0020] S2: The ink droplet data storage will rearrange the ink droplet, change the shape of the ink droplet, and make the ink droplet form an ink droplet cluster. When the air forms turbulence, the position of the ink droplet cluster in the air cannot be changed, so that the ink droplet The balls drip evenly on the paper;
[0021] S3: When ink is ejected, the print head controls the nozzles to eject ink, and ...

The invention discloses an inkjet method for improving printing quality. The inkjet method for improving printing quality comprises the following steps: S1, firstly, ink drop data in an ink drop datastorage are modified; S2, the ink drop data storage enables ink drops to be rearranged, changes the shape of the ink drops and enables the ink drops to form ink drop clusters; and S3, in ink jetting,a print head controls a nozzle to jet ink, and the ink drop clusters in a rearranged shape are jetted from the nozzle. By reorganizing and arranging the shape of the ink drops, the weight and the shape of the ink drop clusters are changed, the ink drop clusters can uniformly fall onto paper, the influence of turbulence on the ink drop clusters is reduced, printing points on the paper are uniformlyarranged, the quality of the printing points is improved, the printing quality of pictures and shading is more obvious, and the problem that the ink drops with smaller mass form regular convergence in the air under the effect of turbulence, the ink drops cannot uniformly fall on the paper, the situation that black and gray appear on printing points occurs, and the printing quality is influenced is avoided.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet method for improving printing quality. Background technique [0002] In inkjet printing, the size of the ink droplets ejected from the nozzle is generally 5 / 7 / 12PL. Due to the different sizes of the ink droplets, when the ink droplets fall vertically, the air around the ink droplets will flow upward, and when the paper moves It will also drive the flow of air to form the gap airflow between the nozzle plate and the printing paper. The upward air flow and the airflow of the paper moving form a turbulent flow, such as Figure 2-4 As shown, the reason for the formation of turbulence, under the action of turbulence, the ink droplets will converge regularly. When these ink droplets fall on the paper, it will cause black and gray on the paper, resulting in the printing of pictures or shading The quality has deteriorated, so it needs to be improved.
